Installation artwork, Public art installation in Geneva, Switzerland

Neon Parallax is a public art installation in Geneva, Switzerland, with thirteen neon works placed on rooftops around the Plaine de Plainpalais. The project, led by the city's contemporary art funds, features pieces by Swiss and international artists, each displayed for a limited period.

Neon Parallax began in 2006 as an initiative of the city's contemporary art funds, with the first works installed on rooftops in 2007. New phases have been added over the years, and the sixth phase was inaugurated in January 2026.

The project borrows the idea of advertising signs from the nearby lakefront and turns commercial slogans into artistic messages. Each work is created by a different artist, giving the square a changing open-air gallery that locals and visitors can enjoy without entering a museum.

The works are scattered on rooftops around the Plaine de Plainpalais, so the best way to see them is to walk around the square and look up. They are most visible after dark, when the neon lights stand out against the night sky.

The project takes its name from the optical effect of parallax, playing on the similar diamond shapes of the Plaine de Plainpalais and the lakefront district. Each rooftop work is loaned by the building owner for a maximum of ten years, so the collection changes gradually as pieces are removed or replaced.
